4vir4ik [10]

ANSWER

Option C and E

EXPLANATION

An arithmetic sequence has a constant difference among the consecutive terms.

The sequence

$18,5.5,-7,-19.5,-32,...$

has a constant difference of -12.5

$d = 5.5 - 18 = - 7 - 5.5 = - 19.5 - - 7 = - 32 - - 19.5 = - 12.5$

The sequence

$16,32,48,64,80,...$

also has a common difference of 16

$d = 32 - 16 = 48 - 32 = 64 - 48 =80 -64 = 16$

Therefore correct answers are C and E

A poker hand consisting of 9 cards is dealt from a standard deck of 52 cards. Find the probability that the hand contains exactl

Andrew [12]

Answer: $\dfrac{^{12}C_{6}\times^{40}C_3}{^{52}C_9}$ or $\dfrac{228}{91885}$ .

Step-by-step explanation:

Given : A poker hand consisting of 9 cards is dealt from a standard deck of 52 cards.

The total number of cards in a deck 52

Number of faces cards in a deck = 12

Number of cards not face cards = 40

The total number of combinations of drawing 9 cards out of 52 cards = $^{52}C_9$

Now , the combination of 9 cards such that exactly 6 of them are face cards = $^{12}C_{6}\times^{40}C_3$

Now , the probability that the hand contains exactly 6 face cards will be :-

$\dfrac{^{12}C_{6}\times^{40}C_3}{^{52}C_9}$

$=\dfrac{\dfrac{12!}{6!6!}\times\dfrac{40!}{3!37!}}{\dfrac{52!}{9!\times43!}}\ \ [\because\ ^nC_r=\dfrac{n!}{r!(n-r)!}]\\\\=\dfrac{228}{91885}$

Hence, the probability that the hand contains exactly 6 face cards. is $\dfrac{228}{91885}$ .

Answer it pls and explain too

snow_tiger [21]

Answer:

y-intercept: (0, 5); slope: 1/4

Step-by-step explanation:

The slope (m) is found from ...

m = (y2 -y1)/(x2 -x1)

Using the first two points in the table, this is ...

m = (8 -6)/(12 -4) = 2/8 = 1/4 . . . . . eliminates choices A and C

Then, the point-slope form of the equation of the line can be written as ...

y -y1 = m(x -x1)

y -6 = (1/4)(x -4) . . . fill in known values

y = 1/4x -1 +6 . . . . . add 6

y = 1/4x +5

Then the value of y when x=0 is ...

y = 0 +5 = 5

So, the y-intercept is (0, 5) and the slope is 1/4, matching the last choice.
